Licensing and Pricing

ILNumerics offers two main software packages: The Computing Engine and the Visualization Engine. Both are enhanced by several toolboxes. The Visual Studio Tools and a Maintenance Subscription are included. 

Software Options

Computing Engine (.NET)

The Computing Engine is based on the array classes, in Matlab(R) style. Additionally, it contains elementwise manipulation functions and linear algebra functions in .NET. The numpy package adds all numpy NdArray features to ILNumerics arrays. In order to facilitate implementation and debugging we incorporated all Visual Studio tools for free.

Visualization Engine (.NET)

The Visualization Engine comprises all plot and graph functionalities in 2D and 3D. This also includes the GUI functionality. For easy data handling we also integrated our array class. To support you during development and debugging, you will also have access to all our Visual Studio tools for free.

Toolboxes (.NET)

Several toolboxes are available as addition to the base functionality of both engines. Choose from the following: Interpolation, Optimization, Machine Learning, HDF5, Statistics, or Drawing Extensions. 

Array Visualizer (C, C++, .NET, Fortran)

Users of either one: the Computing Engine or the Visualization Engine get access to our famous Visual Studio Tools for free. But even if you decide to work without ILNumerics you can still use the Array Visualizer to work with your C#, Visual Basic, F#, Fortran (ifort) or even C/C++ arrays. The Visual Studio extension can now be licensed separately.

License model


A Subscription is our 'everything included' model. For one year our support team will provide you with support and all updates. While under maintenance you can develop, execute and redistribute as much as you want. When the maintenance expires you still have perpetual and royalty-free execution and redistribution rights. That means, even after your subscription ran out you can keep compiling your (unchanged) code, run and distribute your program without further fees. It is only the development - the authoring of code - where you gain great advantage and so we charge for a license here only. Hence, a renewal will only be required in order to perform changes to your code.
